crypto_rng_seedsize9
Obtain seed size of rng
Usage
int crypto_rng_seedsize(struct crypto_rng * tfm);
Arguments
tfm
cipher handle
Overview
The function returns the seed size for the random number generator referenced by the cipher handle. This value may be zero if the random number generator does not implement or require a reseeding. For example, the SP800-90A DRBGs implement an automated reseeding after reaching a pre-defined threshold.
Return
seed size for the random number generator
